What materials is corrugated cardboard made from and how much recycled fiber does it contain?
Corrugated cardboard is a packaging material made of glued flat and fluted (wavy) paper layers. These layers can be produced from both recycled (secondary) and virgin fibers, i.e. fibers obtained directly from wood.
If all layers of corrugated cardboard were made entirely from recycled fiber, it would be considered 100% recycled corrugated board. However, such material is less resistant to moisture and mechanical stress (compression, crushing). For example, a shipping box made from this type of board may not sufficiently protect the product if it is transported over longer distances and periods (e.g., from Lithuania to Europe or the USA).
In practice, at least one layer of corrugated cardboard is often made from virgin fiber to ensure sufficient strength and better moisture resistance.
Typical composition:
- 70–80% recycled fiber
- 20–30% virgin fiber (for strength and quality)
This combination allows packaging that:
- is strong enough for transportation
- meets quality requirements
- remains environmentally friendly
Is it possible to obtain exact data on recycled content?
Yes. MAZUS can provide a certificate for a specific production batch indicating the exact percentage of recycled fiber used in the packaging.
